Provide option for exact Wilcoxon Signed Rank even for n > 20It would be nice to have an option to request exact test for the Wilcoxon Signed Rank test, even for n>20 where a 1970's-era approximation is currently used instead. We have colleagues who are running into collaborators/experts outside P&G who are using the exact Wilcoxon test and our P&G people are unable to replicate the analysis with JMP.
Generally it looks like we are talking about wanting the exact calc for sample sizes in the 20-35 range, but I imagine that simply changing the cutoff may still bring the problem back in the future. Being able to trigger the exact test by red triangle (with a warning that much time may be required, or a time estimate of how long it might take) would be helpful.

Re: Provide option for exact Wilcoxon Signed Rank even for n>20Hi again, can we get any movement on this feature request? Or even JSL code that implements it if it can't be part of mainline JMP?
